Hi -- I am trying to set up some systems with Pi 3Bs and Piface 2s and touchscreens, and found an interesting power supply oddness.
Everything runs fine (well, currently it won't find the Piface 2, but that's different problem) on the 2.5 amp power supply that came with the Pi, but because I have a number of these, and aim to use larger touchscreens), I bought a 5v 6 amp Orico DCW-4U multi-output charger. The setup won't work on the Orico because the voltage is too low (it measures at 4.7-4.8 vDC).
Is this because the Orico is too er intelligent to act as a simple power supply? It charges cellphones fast and fine, so it's clearly good for some things.
Just wondering before I go and buy different multi-output supplies.
